Firstsawyou opened a new issue #2809:
URL: https://github.com/apache/apisix/issues/2809
### Issue description
We all know that apisix supports vars matching rules, similar to this: {var,
operator, val}. But these rules are in the
`apisix/deps/share/lua/5.1/resty/radixtree.lua` file, not in the public method.
Therefore, we cannot reuse these rules. The `match` rule is a very useful
feature. If we add the `match` rule to the `apisix/apisix/core` module, I think
it must be very interesting.
Examples of vars matching:
```
[ "arg_name", "==", "rose" ],
[ "http_appKey", "~~", "[a-z].+" ]
[ "server_port", ">=", "80" ]
```
Supported operators: `==, ~=, ~~, >, >=, <, <=, ip, ip_in`
### Operator list
| Operator | Description | Example |
|-----------|-----------------------|-----------------------------|
| == | equal | {"arg_name", "==", "json"} |
| ~= | not equal to | {"arg_name", "~=", "json"} |
| ~~ | Regular match | {"arg_name", "~~", "[a-z]+"}|
| < | Less than | {"arg_age", "<", 24} |
| <= | Less than or equal to | {"arg_age", "<=", 24} |
| > | more than the | {"arg_age", ">", 24} |
| >= | greater or equal to | {"arg_age", ">=", 24} |
what do you think? Welcome to discuss together.
